This tour is given to give the feel of the whole chapters plus the type of questions and ways to tackle them.This is quite beneficial for anybody studying One dimensional Motion.
One dimensional Motion is the study of the motion along an straight line.Complete Study material has been provided at the below link
We often comes across the problems in mechanics where we need to apply the law of conservation of energy where gravitational potential energy or gravity is involved . For solving such problems you can consider the following problem solving strategy,
Acceleration Formula Acceleration is the rate of change of velocity with time.It is a measure of the change in the velocity of an object per unit time and mathematically acceleration formula is given as For describing average acceleration, we first consider the motion of an object along straight line. Suppose at time t1 object is at point P moving with velocity v1 and at time t2 it is at … Continue reading Acceleration formula Explained with Examples
What is Equilibrium
A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion
The general conditions for equilibrium are as follows
(i) The total force must be zero
(ii) The total torque about any axis must be zero.
In many cases it is convenient to consider torques about axes through the centre of gravity.
Types of equilibrium
We can divide the equilibrium into two categories With respect to the state of a body
1. Static equilibrium.
2. Dynamic equilibrium.
What is Periodic Motion : In Physics, a motion that is regular and repeating is called Periodic Motion. The time to complete one full motion is called the Time period of the Periodic Motion
What is SHM: A Simple Harmonic Motion is a special case of Periodic motion where a physical quatity varies sinusoidally.In this Periodic motion the restoring force is directly proportional to the displacement. The object oscillates between two position and Motion is sinusoidally in nature.
A non inertial Frame of Refrence is the frame of refrence which is having acceleration a. Example Free Falling elevator
Newtons law are valid in inertial frame of refrence only. We cannot apply them as it is in non inertial frame of refrence as it left out the acceleration of the object because of the frame of refrence.
Let me provide simple example to illustrate this.
A) Normal Force: When we put a book on a table ,the molecules of the book exert downward forces on the molecules of the table.The molecules composing the upper layer of the tabletop move downward until the repulsion of the molecules below balances the forces applied by the book.
